To all whom 6t may concern:

Be it known that l, Nrns H. Anonnson, a citizen of the United States,residing at lvliddletown, in the county of Middlesex and State ofJonnecticut, have invented certain new and useful Improvements in Typeflriting Machines of which the following is a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to typewriting inachines, and with regard tocertain more dominant features thereof, to type actions and associatedand co-acting parts thereof.

One of the objects of the present invention is to provide a type actionof simple and practical construction which will be durable and efficientin action. Another object is to provide a type action of the'abovecharacter having a desirable touch and capable of being operated at highspeed. Another object is to provide a type action of the above firstmentioned character which will be comparatively noiseless in operation.A further object is to provide practical means for mounting andconnecting the various parts so as to enhance their case of movement andreduce wear. Other objects will be in part obvious and in part pointedout hereinafter.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth, and the scope ofthe application of which will be indicated in the following claims.

In the accompanying drawings wherein is shown one of the variouspossible embodiments of this invention,

Figure 1, 2 and 3 are elevational views of a type action and co-actingparts suiiicient in detail to understand the application of the presentinvention, in normal, intermediate, and printing positions,respectively;

Fig. 4: is a plan view showing a plurality of type actions in theirradially disposed relation to the printing point;

Figs. 5, 6 and 7 are detail views showing the manner of connecting thetype barto the actuating mechanism.

Fig. 8 is a detail perspective View of a pivot member, and

Fig. 9 is a-detail perspective view of a part of the type action.

Similar reference characters refer to similar parts throughout theseveral views of the drawings.

Referring now in detail to the accompanying drawings, and moreparticularly to Fig. l, a cylindrical platen roller 1, here showndiagrammatically in section, is provided with a fiat metallic platen 2.The platen roller is mounted in any suitable form of verticallyshiftable carriage, not herein shown, movable in the well-known mannerfrom right to left, under the action of an escapement mechanism 3operated at each actuation of the machine. Each heylever 4. is connectedwith a type carrier 5 mounted to slide back and forth relatively to theplaten by means of suitable pressure multiplying and speed controllingelements as will now be described in detail.

The type carrier is provided at its rear end with three type 6 forprinting difierent case characters when co-acting with the fiat platen 2as the carrier slides rearwardly between a base-plate 7 and a top plate8 in the upper rear part of the machine. The carrier is held and guidedin its movement by upwardly and downwardly projectin pins 10 and 11,mounted in the bottom an top plates respectively. To the central partand at either side of the type carrier is connected a pair ofsubstantially flat sheet metal links 12 of more or less resilientmaterial which are adapted to be snapped over a central pivot member 13,as clearly shown in Fig. 8. The pivotal connection between the typeaction and the type carrier comprises what might be termed a ball andsocket connection, that is, the type carrier is provided with a centralopening having a single flattened side within which is placed thespherical pivotal member 13, having a notch 9 cut in one side to engagethe flattened side of the opening in the type carrier, thus to preventlateral removal thereof when assembled. The ivotal member is alsoprovided'with a stu at each side thereof adapted to engage openings inthe ends of the duplex links 12 which are sprung into position thereoverin the manner shown in Figs. 5 and 6. This form of connection permits aslight amount of angular movement between the parts of the type actionand more specifically between the connecting links 12 and the typecarrier itself, as well as providing a more simple form of connectionpermitting greater ease and a less expense in assembling and changingarts.

T e links 12 are connected at their central portion by means of a stud14 to prevent spreading and are also provided with a p votal connectionat their opposite ends with a pairiof links 15, the opposite ends ofwhich are in turn pivotally mounted upon an L-shaped bracket 16 mountedon a front.

plate 17 of the frame of the machine.

This bracket is capable of adjustment in a fore and aft direction bymeans of a setscrew '18 engaging a tapped-out recess in the front walland is held in adjustment by means of a verticall disposed clamp screw20 engaging a simi arly intermediate adjacent actions, as clearly shownin Fig. 4. By loosening the clamp screw 20 between any two adjacentactions, the adjusting screw 18 of' either action may be turned in onedirection or the other to vary the limit of throw of the type carrier, I

thus regulating the pressure with which the type co-acts with the papercarried by the platen. As the links connecting the bracket and the typecarrier form a toggle which assumes extended position, as shown in Fig.3, when the. type action is actuated, the

limit of hrow of any type carrier can thus be positively adjusted andthe pressure of all thetype actions made uniform, thus producing atypewritten page which will be conspicuous for its absence of extremely.heavy or light printed characters.

7 The link 15 is composed of two parts, one

upon each side of the bracket, and each part is provided with an off-setportion 21 to which is pivotally connected the rearward arm 22 of amomentum acquiring means, preferably a momentum accumulator weight 23,which arm in turn, is pivotally connected near its middle to the up-,

per arm 24 of a sub-lever, preferably a bell-crank lever. Thisbell-crank lever is composed of two parts mounted on either side of thebracket 16 and pivoted at 25 on the lower part thereof as shown clearlyin Fi 9.

This bell-crank lever is provided with two arms 26 and 27 extendingforward and rearward, respectively, from the pivot 25. The forward arm26 is adapted to co-act with a pad 29 of felt or other suitablesemiresilient material mounted upon a support 28 in the front wall 17 ofthe machine when the type action is moved to printing position. The reararm 27, which is the longer tapped-out recess of the two, is providedwith an upper convex surface and is adapted to coact with a secondsub-lever 3O pivotally mounted at its wire 32, upon which the sub-lever30 is mounted, is common to all of the type actions. As herein shown,wire 32, upon which the open forked end 31 of the lever 30' -is mounted,is reduced or flattened on one side. This form of constructionfacilitates the assembling or removal of the lever, for it will be clearfrom the drawings that by swinging the lever 30 downwardly into avertical position, after removing the action and disconnecting the pullwire, the reduced or flattened portion of the wire 32 will then occupy arelative position parallel to one of the straight sides of the open end,thus permitting the lever 30 to drop away therefrom.

Near'the forward end of the lever 30 is pivotally connected a pull wire33 provided with a s'uitable adjustable connecting means or clip 34, thelower end of which is connected with the body portion of the keylever 4.I

It will thus be seen that as the key-lever 4 is depressed, or moved onits printing actuation stroke, the lever 30 and rear arm 27 of the bellcrank sub-lever will have'a rocking or heel and toe action, the pointsof contact or power transmitting portions, of the su -leversprogressively approaching the fulcrum of the bell crank lever.

initial engagement between these parts when the action is in normalposition provides a relatively large leverage for the bell crank lever,which moves the type carrier toward theprinting position, thus producingan easy and desirable initial touch. However, as the key-lever continuesits downward movement under-the touch of the operator, the point ofcontact between the lever 30 and the bell crank lever arm 27 movestoward the pivot point 25, thus reducing the leverage on the bell cranklever, but increasing its rate of movement, thereby materiallyincreasing the manifolding properties of the action as a whole.

In order to further increase the pleasantness of touch in an action ofthis character,

the key-lever is composed of two parts, one

by a pad 38 of felt or other semi-resilient 54 from the frame of themachine.

- but straddling the universal bar.

material positioned to receive and arrest the forward end 40 of themember 35, The upward movement of the key-lever is limited by a similarpad 41 mounted at the top of a comb member 42 adaptedto guide thekey-lever 4 in its up and down movement. It will thus be seen that asthe key-lever 4 is depressed, the body portion 35 co-acts with the stop38 and its movement i arrest ed. The key itself, however, being mountedupon the part 4 of relatively lighter material presents a certainresiliency to the finger of the operator which renders the rapidlyrepeated operations less tiresome.

A return spring 43 is adjustably connected to a downwardly projectinglug 44 on the under side of the key-lever. The other key-levers (notshown) are provided with similar springs, all of which are connected toa single yoke 45 which in turn is connected by means of a link 46 to afixed portion 47 of the front part of the frame. By turning a holdingnut 48 on the forward end of the connecting link 46 the tension of allthe key-levers may be simultaneously regulated. 1

As these several features regarding the key-lever construction andadjustment form no part of the present invention specifically, except inso far as certain features co-act with the type action as a whole, it isthought to be. unnecessary to describe the same more in detail, as theywill form the subject-matter of one or more separate applications.

Instead of positioning the universal bar beneath the key-levers, as inmany forms of front-strike machines, it is in this embodiment positionedin the upper front part of the machine whereby it may be actuateddirectly'by similar elements in each type action. -As herein shown, theuniversal bar comprises a frame 50 in the form of an arc and ispositioned just below and in rear of the pivot point 25 of each bellcrank lever. A fork or yoke 51 is swiveled on the rearwardly extendingarm 27 near the point of connection of a return spring 52 of eachbellcrank lever and normally rests slightly above The universal bar ispivotally supported by means of a plurality of arms 53 of substantiallythe same length connected to dependingbraceflzs e lower part of theuniversal b'ar frame is pivotally supported at the ends of three arms 55of substantially the same length, only one of which is herein shown,connected respectively with either end and the center of a universalrock shaft 56. The rock shaft is lhe oscapement mechanism 3. The pullwire 58 passes freely through an opening 60 in the transverse beam 47 ofthe frame of the machine as well as the comb 42 for the key levers. Aself-locking adjusting nut 61 is provided at the forward end of the pullwire for adjusting the distance between the fork and universal bar, andanother 62 at a point in the rear of the beam, between which second nut62 and beam 47 is coiled a spiral return spring By means of theseadjusting means the relation of the universal bar 56 to the bell cranklever may be regulated as well as the proper timing of the eseapementmechanism and tension of the action as a whole. However, as thesefealures form no part of the present invention specifically, except in.so far as they co-act with the type action, a more detailed descriptionof the various features and advantages is believed to be unnecessary.

The operation of the present device is substantially as follows:

Assuming a machine to be in normal position, as shown in Fig. 1, as thekey-lever 4 is depressed, or printingly actuated, movement istransmitted to the pull wire 33 connected with the body portion 35 ofthe keylever to the forward end of the lever 30 which-in turn rocksdownwardly upon the upper curved surface of the rear arm 27 of the bellcrank-lever. This movement causes the upper end of the bell crank arm 24to swing rearward on its rinting movement about its pivotal point ofsupport 25, which in turn carries the rear arm 22 of the momentumaccumulator rearward and downward. As the movement continues, the toggleformed by the links 15 and 12 moves toward straightened position, asshown in Fig. 2. Likewise the rear arm 22 of the momentum accumulatorand the upper or longer arm 24 of the bell crank lever assume apartially extended reverse toggle. As soon partially on the length ofits swinging 120 radius, in riarward and downward direction to completethe printing operation by forcing the type carrier to the printingplane, as

shown in Fig. 3, that is, with the type in contact with the papercarried by the platen. 125' It will be noted that at this point thetoggles formed by the links 12 and 15 as well as the reverse'toggleformed by the rearwardly extending arm 22 of the momentum accumu-.

lator and the upwardly extending arm 24 of 13a the bell crank leverassume a straightened positions. It will also be noted that in theposition shown in Fig. 3, the power transmitting portion of the rear arm27 of the bell crank lever has moved out of contact with the powertransmitting portion of the lever 30 and has placed the spiral returnspring 52 under tension; there is therefore nothing to prevent themomentum accumulator from erformin its natural tendency to rebound fromstop ance of this return spring, to carry the type immediately out ofengagement with the platen regardless of the release of the keyl5 lever.It is during the final movement, that is, while the carrier is movingfrom the position shownin Fig. 2 to that shown in Flg. 3, or whilemovement of the type carrier is effected by the energy stored in weight23,

v that the fork 51 carried by the rear arm 27 of the bell crank levercoacts with the universal bar 50 tourge the same downward.

This downward movement of 'the universal bar will, through itsconnecting mechanism, rotate the universal rock shaft 56, which in turn,through the pull wire 58, actuates the dog rocker of the escapementmechanism 3.

Owing to its mounting the universal bar will have a slight movementlongitudinal of the sub-lever, or arm 27, and the element 51, be-

ing movably connected to said sub-lever will readily follow thislongitudinal movement and be retained in pressing position, thusdispensing with substantial friction between the universal bar and thissub-lever during actuation of the escapement.

The escapement mechanism which is preferably of the reverse style, thatis, with the fixed dog normally in engagement with the teeth, willcomplete its operation on the down stroke of the key lever when normallyoperated, thus permitting the carriage to move a letter space distancefrom the right to left. The movement of the type from the 45 positionshown in Fig. 2 to that shown in Fig. 3, and return, is almostinstantaneous and yet being pressure-operated by means of toggles andpower multiplying devices interposed between the type carrier and thekey lever, its operation is substantially noiseess. Y

WVhen the key-lever is released the parts naturally return to theposition shown in" Fig. 1, under the action of the several re- 55 turnsprings 43, 52 and 63 which all co-act one with the other to produce thedesired result.

A pad 64 is provided on the upper surface of the front wall of themachine having an upwardly and rearwardly inclined upper surfacecoacting with an inclined surface of the under side of the momentumaccumulator weight 23 adapted to cushion its return and prevent arebound thereof. The 65 center of the weight23 does not move in the ar29 with the assist-' are of a circle, due to its compound pivotalconnections and the path of travel of the final portion of its returnmovement is in a substantially straight line at a very slight angle tothe upper surface of this pad. Re- .0

ferring to Fig. 1, it will be seen that the 'weight is in its mosteffective forcing POSI- tion than it would be if said angle were acuteinitially.

It will be noted that the various parts comprising the presentembodiment of the invention are so constructed and connected as to causea minimum amount of wear; the various cushioning and spring devices forarresting the movement of such movable parts produce, in their co-actionwith the other parts, a machine which is substantially silent in itsoperation.

It is thus seen that this'invention provides a practical and simpleconstruction which is durable and highly eflicient in action and onethat is adapted to accomplish, among others, all of the objects andadvantages above set forth.

As many changes could'be made in the above construction and manyapparently widely diflerent embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative and not in a limiting sense.
